Metabolites differing by age in marmosets.

Female and male marmosets were grouped according to age as younger (y, 2 to 7 y) and older (o, 8 to 15 y). A-C, metabolites higher in older than younger. D and E, metabolites higher in younger than older. Following ANOVA, post-hoc tests showed differences between groups as indicated: c, younger versus older females; d, younger versus older males. Group sizes were: females, 12 y, 12 o: males 13 y, 13 o.

研究人员按年龄将雌性和雄性狨猴分为青年组（y，2~7岁）与老年组（o，8~15岁）。图A至C中，老年组的代谢物水平高于青年组；图D与E中，青年组的代谢物水平高于老年组。经方差分析（Analysis of Variance, ANOVA）后，事后检验（post-hoc test）显示组间存在如下差异：c为雌性青年组与老年组的比较；d为雄性青年组与老年组的比较。各组样本量如下：雌性青年组12只、雌性老年组12只；雄性青年组13只、雄性老年组13只。
